使用C#将数据从excel文件中导出实例代码

使用C#讲数据从excel文件中导出实例代码如下：

private void doExport(DataSet ds1,string[] str)
{
System.Reflection.Missing oMissing = System.Reflection.Missing.Value;
_Application xlApp = null;
_Workbook xlWorkbook = null;
_Worksheet xlWorksheet = null;
try
{
xlApp = new ApplicationClass();
xlApp.Visible = true;
xlWorkbook = xlApp.Workbooks.Add(oMissing);
xlWorksheet = xlWorkbook.Worksheets.Add(oMissing, oMissing, 1, oMissing) as _Worksheet;
xlWorksheet.Name = "福州市盲人易做图单位信息";
Excel.Range r;
r = xlWorksheet.get_Range(xlWorksheet.Cells[1, 1], xlWorksheet.Cells[1, 7]); //取得合并的区域
xlWorksheet.get_Range(xlWorksheet.Cells[1, 1], xlWorksheet.Cells[1, 7]).Font.Size = 20;
xlWorksheet.get_Range(xlWorksheet.Cells[1, 1], xlWorksheet.Cells[1, 7]).RowHeight = 45;
xlWorksheet.get_Range(xlWorksheet.Cells[2, 1], xlWorksheet.Cells[2, 1]).ColumnWidth = 5;
xlWorksheet.get_Range(xlWorksheet.Cells[2, 3], xlWorksheet.Cells[2, 3]).ColumnWidth = 33;
xlWorksheet.get_Range(xlWorksheet.Cells[2, 6], xlWorksheet.Cells[2, 6]).ColumnWidth = 15;
xlWorksheet.get_Range(xlWorksheet.Cells[2, 7], xlWorksheet.Cells[2, 7]).ColumnWidth = 50;
r.MergeCells = true;
r.HorizontalAlignment = Excel.Constants.xlCenter;
xlWorksheet.Cells[1, 1] = "福州市盲人易做图单位信息";
xlWorksheet.Cells[2, 1] = "ID";
xlWorksheet.Cells[2, 2] = "单位编号";
xlWorksheet.Cells[2, 3] = "单位名称";
xlWorksheet.Cells[2, 4] = "单位类型";
xlWorksheet.Cells[2, 5] = "负责人";
xlWorksheet.Cells[2, 6] = "联系电话";
xlWorksheet.Cells[2, 7] = "联系地址";
for (int i = 0; i < ds1.Tables[0].Rows.Count; i )
{
xlWorksheet.Cells[i 3, 1] = i 1;
xlWorksheet.Cells[i 3, 2] = ds1.Tables[0].Rows[i][1].ToString();
xlWorksheet.Cells[i 3, 3] = ds1.Tables[0].Rows[i][2].ToString();
xlWorksheet.Cells[i 3, 4] = ds1.Tables[0].Rows[i][3].ToString();
xlWorksheet.Cells[i 3, 5] = ds1.Tables[0].Rows[i][4].ToString();
xlWorksheet.Cells[i 3, 6] = ds1.Tables[0].Rows[i][5].ToString();
xlWorksheet.Cells[i 3, 7] = ds1.Tables[0].Rows[i][6].ToString();
}
xlWorkbook.SaveAs(Hiddenfield1.Value, oMissing, oMissing, oMissing, oMissing,
oMissing, Excel.XlSaveAsAccessMode.xlShared, oMissing, oMissing, oMissing,
oMissing, oMissing);
xlApp.Quit();
}
catch
{
}
finally
{
System.Runtime.InteropServices.Marshal.ReleaseComObject(xlApp);
xlApp = null;
GC.Collect();
}
}
格式控制
xSt.get_Range(excel.Cells[1,1],excel.Cells[1,1]).HorizontalAlignment = Excel.XlHAlign.xlHAlignCenter;//对齐方式
xSt.get_Range(excel.Cells[1,1],excel.Cells[1,1]).Select();//设置选中的部分的颜色
xSt.get_Range(excel.Cells[1,1],excel.Cells[1,1]).Interior.ColorIndex = 19;//设置为浅黄色，共计有56种
xSt.get_Range(excel.Cells[1,1],excel.Cells[1,1]).Font.Bold = true;//字体类型
xSt.get_Range(excel.Cells[1,1],excel.Cells[1,1]).Font.Size = 22;//字体大小
xSt.get_Range("a1","a1").ColumnWidth = 20;//列宽度
object oo = false;
xSt.get_Range("A1","B1").Merge(oo);//合并单元格
